single phase prepaid meter

Product Brief introduction

The DDSY***8type single-phase electronic watt-hour meter adopt exclusive use LSI,the device typifying few periphery component, simple structure , high reliability, low power consumption, long life etc, is suitable for the single-phase AC active electric energy with rated frequency of *0Hz;the performance is in conformity with the technical requirements for single-phase electronic watt-hour meter stipulated in GB/T****5 **1 ****8 Class I and 2 Static AC Active Watt-hour Meter standard;

Function and Feature

Measure active electric energy,do not need calibrate for long-term operation;

Long service life,accessiblel0 years;

Sampling current at the same time between phase line and middle line,use the larger as valid sampling,abstraction -of-electricity prevention one fire one ground thoroughly;

Adopt exclusive use LSI and SMT surface fixing technique,having advance technology and dimple structure;

Adopt the latest oversea electric energy special integration circuit,greatly improved dynamic working range of Meter;

Have good mistake linearity in the range of5%lb-lmax

Adopt high reliability and long life electronic component,so the Meter assume feature of high reliability and long life;

Low self power consumption,mighty overload
